DSIP Research Overview

Delta sleep-inducing peptide (DSIP) is a nine-amino-acid neuropeptide first isolated in 1977 from the venous blood of rabbits during induced slow-wave sleep. DSIP is supplied for qualified in-vitro laboratory research and analytical use only.

Compound profile

  • Compound class: Nonapeptide neuropeptide
  • Sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE)
  • Molecular weight: ≈ 848.8 g/mol
  • CAS number: 62568-57-4
  • Form: Lyophilized powder in a sealed vial
  • Testing: Third-party HPLC purity and identity, batch-matched COA

Research context

DSIP research spans sleep architecture and slow-wave (delta) sleep, circadian and neuroendocrine regulation — including corticotropin and luteinizing-hormone signaling — and stress-response models. Its endogenous receptor and precise mechanism remain under investigation, making it a continued subject of neuroendocrine research.

Storage and handling

Store unopened lyophilized vials sealed and protected from light — at −20 °C for long-term storage, or 2–8 °C for short-term use. Once reconstituted, keep refrigerated at 2–8 °C, minimize freeze–thaw cycles and rely on your laboratory’s own validated stability data.

Quality and documentation

Every lot is third-party tested, and the Certificate of Analysis is matched to the exact batch you receive — look it up any time on the COA page. Browse more Neurological & Cognitive Research, or see related compounds: PINEALON, Selank 10MG.
